If you are a gamer and want to play games on your laptop than go for the Acer. It will be better for gaming because it has a dedicated Graphics Card - Nvidia Geforce gt540m. Dedicated Graphics Cards provide better performance in gaming.
If you are not a gamer than go for the Lenovo Ideapad z580. It has Intel HD 4000 Graphics Chip which is OK for Youtube and Movies but not for gaming. It has a better screen than the Acer's.
Go for the acer
Depends on your usage. If you want to do gaming, the lenovo won't give you a satisfactory experience. The video is integrated which is okay for Internet and some movies. The full hd resolution as well takes more resources so it probably won't do well with heavy games and bluray movies. If you don't care about the screen resolution that much, the Acer seems the way to go.
These are both have a good configuration but I like Acer. I'm a acer user. I'm satisfy.
